New subatomic particle with four 'flavours' discovered

February 28, 2016 15:26

Scientists have discovered a new elementary particle - a rare tetraquark consisting of four distinct types or 'flavours' of quarks.

Quarks are point-like elementary particles that typically come in packages of two or three, the most familiar of which are the proton and neutron (each is made of three quarks).

Tetraquarks - four quarks together - are much rarer and are not well understood.

There are six types, or "flavours," of quark to choose from - up, down, strange, charm, bottom and top. Each of these also has an antimatter counterpart.
